A local file inclusion vulnerability exists in Genuitec Secure Delivery Center (SDC) in versions lower than 5.4.7. This vulnerability can be exploited to gain admin access to the application. To Exploit the LFI, an attacker can insert a series of “..\”‘s into the URL to move up the directory structure. The attacker will need to…

Anytime I find a file upload form I test it. Best case scenario is that I can upload a reverse shell in a scripting language available on the webserver. If the application is running in PHP or ASP for example, it becomes quite easy. If I can’t get a backdoor uploaded, I will attempt to…

While performing a web application penetration test, I stumbled upon a parameter with some base64 encoded data within a POST parameter. Curious as to what it was, I send it over to Burp decoder. After two rounds of URL decoding and one round of Base64 decoding, I had what appeared to be a serialized Java…

I’m always on the lookout for VulnHub VMs that teach real pentesting skills, and are not just puzzles. I like them to be practical, and force you to learn techniques that you would use in the real world. I feel Donkey Docker is one of these challenges. As always we can begin with an nmap…

Recently I was performing a penetration test and came across a Server Side Include injection bug (SSI). If you are familiar with cross-site scripting (XSS) this type of vulnerability will sound familiar. This is caused by an application taking input form the user, and supplying it in the response from the server. The mitigations are…

Dell Foglight for Virtualization is an infrastructure performance monitoring tool that can also be used to manage systems as well. It comes configured with a default username and password of “foglight”. It is possible to execute code on the host itself through an integrated scripting console. By browsing to Homes -> Administration And then…

There are many ways to run a phishing campaign. The most common of them all is a typical credential harvesting attack, where the attacker sends an email to the target enticing them to click a link to a spoofed website. Running these campaigns are fairly straight forward, and a couple of tools make this…

Sedna is the second vulnerable VM released by hackfest.ca this month. Much of the first steps of enumeration will be similar to that of my write up for the first VM in the series. The first thing I start with is an Nmap scan. The output is below, shortened for brevity. root@kali:~# nmap 10.0.1.22 -p-…

A relatively new set of VulnHub CTFs came online in March 2017. This post is about the first and easiest one, named “Quaoar“. This post will be a walk-through of my exploitation of this system. The first thing I like to start off with on any box is a full TCP port scan. When you…

Synergy is a type of mouse an keyboard sharing software. When configured, moving your mouse off the screen will allow you to control another system that is also set up with Synergy. Below is a YouTube video from Synergy on how it works: The way this works is one host acts as the Synergy…

During an external penetration test, you may be tasked with gaining access from the internet with no knowledge of the a target environment. After hitting all known servers and web applications with various scanning tools, you have nothing. Searching open source information such as database breaches…

Applications that are in use on Macs often times are under less scrutiny for security compared to their Windows alternatives. When researching popular apps in use on OS X I found an app on the iPhone called HippoRemote. It appears to be quite popular, with a combined 7,558…
